Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555228, here are decompositions:

  • 7 + 555221 = 555228
  • 19 + 555209 = 555228
  • 61 + 555167 = 555228
  • 109 + 555119 = 555228
  • 131 + 555097 = 555228
  • 137 + 555091 = 555228
  • 151 + 555077 = 555228
  • 199 + 555029 = 555228

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 555,228 and was likely granted around 1895.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 555228 first appears in π at position 887,488 of the decimal expansion (the 887,488ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
